Maybe you are missing the correct CODEC, see:

As the article is quite old (2009) it might not work anymore on Windows 10.

I did not test this example with VS 2008 yet. DirectShowLib V2.0 is ok, I think you should also use option VS2005 (also needed for VS 2005). Probably you have to correct the Direct.Capture directory and the directory/filename of theDirectShowLib file. That is system dependent.
It could be that the example program needs an older
DirectX version, probably DirectX 9. See:
